San Diego County, San Diego Rat Control Situation:
Hi David, Is a UV blacklight still useful, exterior-wise, if it rains after the rodents leave their urine stains? I am in the process of performing exterior maintenance to better exclude my roof rats. 1) I have a 25 year old cedar shake roof in San Diego California with openings under each shake along the rake edge of the roof at the gable ends of my house. There's no drip edge, i.e. under the shakes I have roofing paper (now somewhat curled) that runs more or less up to and rests right atop the fascia board. Because I have skip sheathing, and since the cross section of a shake is a wedge that is up to one inch at the upper, thick end, this appears to create many huge entry points along the rake edges even though the sheathing is rabbeted into the fascia board. As a result, I'm thinking of getting a UV blacklight to use outside the house to sleuth for urine stains along the upper edge of the gable end shakes and fascia boards. My question is, how easily does the winter rain wash away the urine, rendering this a pointless exercise? 2) I noticed a new product called "rat-out gel" and was thinking of applying it along the rake edges mentioned above. Or, maybe I should just buy many rolls of X-Clude and use that instead. Or maybe both. Any comment? Thanks very much for your website, Doug
My response: First off, I do not have experience using UV lights to detect rat urine. But I do suspect that rain will severely limit the effectiveness of this approach. I have never heard of Rat-Out Gel or XClude, but I typically stick to physical barriers rather than repellent type devices. If your roof makes this impossible, you might have a tough time keeping the rats out.
San Diego Rat Control Tip of The Week
What To Do If A Rat Got Inside My House?
Rats are considered as one of the most dangerous household pests due to their destructive nature and their ability to carry diseases and other disease-causing organisms. If you happen to have a rat invasion in your home, you need to find a way to get them out without any further delay.
Rats are naturally sneaky and will always find a way to move around your home without being noticed. As a result of this, getting them out of your house might be quite difficult to do. To help make this easy for you, we will be sharing the simple steps you can take to handle the situation if rats get inside your house.
1. Locate All Their Entry Holes
Rats getting into your home means there are holes around your home big enough to allow their easy passage. Having realized this, the first thing you need to do is to find those holes and seal them up. By doing this, you will be preventing more rats from getting into your home.
2. Clean Your House
Even though rats do infest the cleanest of houses, it important for you to make sure your house is unattractive to rats by clearing all dirt and clutter in and around your home. To do this, take your time to clean your kitchen floor, clear out hidden places that you don't clean regularly, and vacuum the floor of your home to remove food particles. Also, when cleaning your home, you need to make sure your food is kept in a rat-proof container or cupboard.
3. Keep Their Natural Predators
When it comes to getting rats out of your home, one of the best ways to do this is to get their natural predators in your home. For instance, you can get a cat to help hunt them down and keep them away.
4. Trap And Remove
Although the use of lethal traps is an inhumane way to get rid of rats in your home, it is the most efficient method to use. To use this method, all you have to do is get traps from a local store and place them along the route of the rats.
Repeat this same process until you can remove all of the rats in your home.
